Is this just marketing, or did they think it was time for a product line refresh?

I'm always suspicious when a company with a reasonably well reviewed product decides to release a new product at the exact same price point. Makes me wonder if it's not driven by profit generation through lower quality parts. Anybody know what the guts of these things are?

Corsair will most likely be phasing out the VX550 along with most if not all of the TX line. These units are based on CWT's PSH-II platform.
